Handling/Suspension upgrades

Handling modifications are the thing most do first for the 718 Cayman.

Putting a little negative camber on the fronts and a degree or two of toe out, will radically enhance your 718 Cayman in handling and cornering.

Drop the car by as much as 22mm - 38 mm. and fit modified stiffer dampers, bigger drops will need other modifications in most instances.

Our aim in 718 Cayman engine tuning should be to increase peak power and Torque at the top end.

With our advice your 718 Cayman can make some decent track times and yet still reliable daily driver.

Sadly with smaller engine sizes you are wasting your time spending money on modifications, so if this applies to you get yourself an engine swap then apply the following mods.

Tuning modifications.

Typically these performance mods are usually carried out by our members, decide how far you want to go before you begin.

Getting the best modified parts for your planned usage of the car is a time and money saver. Stage 3 (competition) mods just don't work well on the road and will make the car undrivable.

Stage 1 mods: Panel air filter, Lighter flywheel, Alloy wheels, Sports exhaust, Remap, Suspension upgrade (drop 22mm - 38 mm.).

Stage 2 mods: high flow fuel injector, Ported and polished head, Power/Sport clutch, fuel pump upgrades, Fast road cam.

Stage 3 mods: Internal engine upgrades (pistons/head/valves), Competition cam, Sports gearbox, Engine balancing, Adding or upgrading forced induction (turbo/supercharger).

Your aim when tuning the engine should be a wide torque curve. You want to avoid sending all the torque to be at the top end unless you are creating a motor sport car.

The point of our tips is to give a starting base of modifying upgrades and point you in the right direction, our forum is the place to go for detailed advice and tips on your car tuning project, the best tuning modifications and all aspects of modding cars.Fast road cams offer one of the biggest power gains for your money as far as a stand alone modified modifications goes on a NASP engine.

It improves the intake and exhaust flow and increases the power if done right. Ideally you'd add other mods and finish up with a reflashed ECU. TorqueCars would caution you not to go with a competition cam as this affects the engines idling and general town driving characteristics.

You will need to ensure that the engine is not starved of fuel so will need to increase the fuelling.

Frequently power losses, flat spots and erratic idling after uprated mods are done can usually be traced to timing or fuel delivery issues. Improved injectors will enable you to supply sufficient fuel to the engine.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned 718 Cayman's uprated injectors.

Intake and Exhaust Tuning.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car extensively and are finding that the standard air intake has become the bottleneck.

For most 718 Cayman engines TorqueCars would suggest you just go with a washable panel air filter. On heavily tuned engines and turbo vehicles an induction kit will help release the power providing you address the problem of needing cold air.

Sports exhausts will certainly help air flow through the engine but avoid an exhaust that is too wide or you may end up will reduce the flow rate. Stick to 1.5 to 2.5 inches for best results.

Airflow through the head can be dramatically increased with some professional gas flowing. These should match and be setup to take into account any other engine mods. A good multi plate fast road performance clutch will help to keep that power going where it should. Never cut corners or think that the standard OEM clutch to cope. The best mods we recommend for your 718 Cayman are fast road camshaft, remap, induction and exhaust, suspension.

NASP engines do not achieve big power gains if you remap them, unless you have done extensive modifications. With turbocharged engines this is another story. A remapped turbo will give large power gains and fully release the potential power of the engine. The most significant power gains for NASP engines usually involve the addition of forced induction. It is often easier to bolt on a supercharger than it is to fit a working turbo. With a turbo the boost curve is related exponentially to the engine speed making it more challenging to map.

The nice steady boost and rpm characteristics of the supercharger make them easier to map. Adding forced induction will nearly always require a lower compression ratio or water injection.

Alloy wheel upgrades.

Due to the fact that alloy wheels are less heavy they improve performance and they help to cool the brake disks. If you are serious about performance then you will need to carefully choose your tires - ideally with a directional tread pattern tire. Large 718 Cayman alloy wheels can decrease performance. If you get big alloy wheels you will be changing your final drive ratio.

For this reason we would advise sticking to a maximum wheel size of 18 inches, although we know some of our members have gone larger than this with no problems.
